Yosemite National Park – May 4, 2023 – This past weekend right after Yosemite decided it would open the valley early from the flood dangers in the valley lightening, they announced the closure of Hwy 120 (west Entrance to Yosemite national Park. Today via Facebook they allowed us to all know why this is occurring and how long the closure will remain in effect.
It has been discovered The road has a crack that is about 200 feet long and up to four feet deep. The road surface has moved two to three inches vertically and horizontally and is continuing to move. The embankment below the road has moved as much as 15 feet downslope and has significant water flow through it. It is not safe to open the road even to limited traffic, and doing so would likely lead to additional road failure.
Big Oak Flat Road (continuation of Highway 120 west into Yosemite) is closed from just inside the park boundary to Merced Grove. The road will be closed at least until mid-June and possibly into July. We are working with the Federal Highway Administration to start repairs as soon as possible.
Visitors entering Yosemite via Highway 120 from the west can reach Hodgdon Meadow and Hetch Hetchy, but not other areas of the park (including Yosemite Valley).
From Yosemite Valley, visitors can drive up the Big Oak Flat Road to reach the Tuolumne and Merced Groves of Giant Sequoias.
Expected Delays to opening Tioga Pass and Glacier Point roads
Around this time of year as well, visitors start asking about possible opening dates for Tioga Pass and Glacier Point which has been closed for reconstruction for the past year. On their website there is a warning stating that later than normal openings should be expected, possibility of into July before we see access.
One reader this week took these images of Highway 120 towards Tioga pass on his winter adventures.
